Portugal. Afonso VI (1656-1667). Silver 600 Réis Struck over a Pataca Macuquina Coin

The Silver 600 Réis coin of Portugal under King Afonso VI (reigned 1656-1667) was struck over a Pataca Macuquina coin, highlighting intriguing numismatic practices of repurposing or overstamping coins. Afonso VI reigned during a turbulent period marked by the Portuguese Restoration War against Spain. The 600 Réis denomination was used for mid-value transactions and often crafted in silver. Macuquina coins refer to hammered coins with irregular shapes typical of the era. Such overstamping or restriking indicates economic adjustments, transitions, or the revalidation of older coinage. This coin reflects both monetary history and the complex interplay of political authority and currency during 17th-century Portugal. Collectors find these coins significant due to their historical context and the overlay of different minting techniques.
